sometimes get to see the daughter crafts out and about
see this link http://www.craig-group.com/shipping/vessel.cfm
scroll to bottom and look at the daughter craft .......these were £250,000 each at the time probobly more now. not strictly ribs but not far off similar design
BP take SAR very serious ...they bought into a project called Jigsaw and purchased boats and 2 super puma mk11 helicopters and parked them offshore on rigs ....they are kitted out as good if not better than sar choppers and have saved 2 good friends lifes due to heart attacks offshore.
downside to the choppers is they can only carry a handful of men ...upside they are quick to arrive and can operate in most weathers .......i think we stop our flying when waves get above 6 metres due to the standby boats unable to do a rescue after that .......sar choppers can fly in some horrendous conditions ...we refeuled one on deck at 65knots
get to see our frc almost every day when they send the crew out for MOB excersises or more important ....the mail and newspapers ....these guys seem to love the big waves.
